Antibiotic complexed with topoisomerase IV, illustration

---

Illustration of the antibiotic levofloxacin complexed with topoisomerase IV and DNA (deoxyribonucleic acid, blue helix) from a Streptococcus pneumoniae bacterium. Topoisomerase IV is a bacterial enzyme that untangles newly replicated DNA and enables the segregation of daughter chromosomes during replication. Levofloxacin binds to topoisomerase IV and inhibits it, therefore preventing the bacterium from replicating.
